1. Performance-based design optimization using uniform deformation theory: a comparison study
The uniform deformation theory (UDT) is a relatively new concept in structural seismic design optimization. However, the results of optimization based on this theory have not yet been compared with other optimization techniques such as metaheuristics, and the optimality of the designs has been proved only by comparing the results with the conventional design

2. Global optimal path planning of an autonomous vehicle for overtaking a moving obstacle
In this paper, the global optimal path planning of an autonomous vehicle for overtaking a moving obstacle is proposed. In this study, the autonomous vehicle overtakes a moving vehicle by performing a double lane-change maneuver after detecting it in a proper distance ahead. The optimal path of vehicle for performing the lane-change maneuver is generated by a

3. OPACIDADE FONOLÓGICA EM PORTUGUÊS: UMA RESPOSTA VIA TEORIA DA OTIMIDADE CONEXIONISTA PARA UMA QUESTÃO CARTESIANA / PHONOLOGICAL OPACITY IN PORTUGUESE: A RESPONSE VIA CONNECTIONIST OPTIMALITY THEORY TO A CARTESIAN QUESTION
Phonological opacity refers to rules/ processes that should apply in a given context but don‟t or apply even without a visible context. As such processes of underapplication and overapplication are found in the intermediate stages in-between the underlying and surface forms, the Classic Generative Theory (CGT) used to accommodate them without much ado

4. Uma análise dos vocoides altos em português brasileiro : relações entre silabificação e atribuição do acento
In this work, we aim to analyze the way high vocoids behave in relation to syllabification and stress assignment in Brazilian Portuguese (BP). The term ¿vocoid¿ is used here to express a subjacent segment that can surface as vowel or glide. Our objective is to verify in which contexts will surface one or the other. Based on Optimality Theory (Prince and Sm

5. As consoantes geminadas do italiano : análise de sua produção por falantes italianos e por aprendizes brasileiros
In this dissertation, we investigate the geminate consonants of Italian using production data collected from Italian speakers and Brazilian learners who take undergraduate courses at the Italian Section of the Federal University of Rio Grande do Sul (UFRGS). The general question that guided our acoustic and phonological analysis is whether Brazilian speakers

6. Análise do /s/ pós-vocálico no português brasileiro: coda ou onset com núcleo foneticamente vazio?
There has been a lot of discussion about the post-vocalic /s/ and its variable behavior in Brazilian Portugueses, as in Brescancini Brescancini (2002); Callou, Leite, Moraes (2002); Hora (2003); Ribeiro (2006); among others. All of them agree that /s/ occupies the coda position, alternating alveolar (ca[s]ca, me[z]mo, feli[s]), palatal (po[]te, de[

7. As vogais médias em posição pretônica nos nomes no dialeto de Belo Horizonte: estudo da variação à luz da Teoria da Otimalidade
The objective of this research is to analyze the variation of mid-height vowels in pre-stressed-syllable position in nouns spoken in the dialect of Belo Horizonte, taking into consideration linguistic factors and phonological processes, such as vowel harmony and vowel reduction, which interfere with this production. Variation is also studied using Optimality

8. A interferência fonológica do português L1 na aquisição de inglês L2 : os traços [+tenso] e [- tenso]
This dissertation tried to identify the interferences Brazilian Portuguese (BP) has in the acquisition of English as a foreign language, through a corpus made up of fifteen interviews with advance level students of English. This research had as an objective, to investigate the difficulties native speakers of BP find when learning English as a foreign languag

9. ENGLISH INTERDENTAL FRICATIVE ACQUISITION: AN APPROACH BY CONSTRAINS. / AQUISICÃO DAS FRICATIVAS INTERDENTAIS DO INGLÊS: UMA ABORDAGEM VIA RESTRIÇÕES.
In this thesis English interdental fricative acquisition by Brazilians second language learners has been investigated. Data from oral productions of three students groups has been gathered. The first group is composed by sixth semester undergraduate students of UNIFRA English course. The second and third groups are composed by third and tenth semester studen

10. Contribuições na teoria de otimização para alguns problemas de programação infinita e de programação com tempo continuo / Contributions in the optimization theory for some infinite programming problems and continuous time programming problems
In this thesis work it is regarded two type of abstract optimization problems. The _rst one corresponds to the in_nite programming problem. A such problem consists in minimizing a functional subject to an in_nite number of constraints, where the functions involved are dened in a Banach space. The second one is the continuous time programming problem, which c

11. Variação das vogais médias em posição pretônica nas regiões norte e sul de Minas Gerais :: uma abordagem à Luz da Teoria da Otimalidade
The current dissertation presents an analysis concerning the behaviour of the medium vowels, in pre-stress position, based on the data obtained from the dialects of the areas South and North of the State of Minas Gerais. In such areas, an interesting phenomenon is produced, which is basically summarized in the following aspects: in the South area, the presen
